The AT24C01BU3-UU-T is a 1 Kbit EEPROM (Electrically Erasable Programmable Read-Only Memory) from Atmel, now Microchip Technology. It is organized as 128 x 8 bits and utilizes a 2-wire serial interface for communication. The 'END-OF-LIFE' category indicates that this particular part is no longer in production, which can impact its availability and suitability for new designs.

Applications

• Consumer Electronics: Storing small amounts of configuration data in devices such as televisions, set-top boxes, and audio equipment.
• Industrial Control: Used for storing calibration data, sensor offsets, or device-specific settings in industrial equipment.
• Automotive Electronics: Employed for storing parameters, identification numbers, or configuration settings in automotive systems.
• Medical Devices: Storing device-specific parameters and settings in medical instruments.
• Security Systems: Used for storing access codes or configuration settings in security devices.

Features

• 1 Kbit EEPROM: Provides 1024 bits of non-volatile storage.
• 2-Wire Serial Interface (I2C): Uses the I2C protocol for simple and efficient communication.
• Low Voltage Operation: Designed for low-power applications.
• Self-Timed Write Cycle: Automatically handles the write timing, simplifying the interface.
• Write Protection: Prevents accidental data overwrites.
• Small Package: Available in compact packages for space-constrained applications.
